Jet tagging
- Chris Malena Delitzsch (University of Arizona (US))
N-subjettiness has proven to be a powerful tool for discriminating between boosted signal jets (typically boosted electroweak bosons or top quarks) and light QCD background jets. In this talk I will examine how it can be most effectively used in conjunction with prong finding and grooming algorithms to tag boosted top quarks. I will first examine the performance and effect of hadronisation and...
The ATLAS experiment has extensively explored tagging boosted hadronic objects, especially W/Z bosons and top quarks, using featured-based techniques and machine-learning combinations of features. A variety of tagging algorithms for large-radius jets, reconstructed from unified-flow-objects (UFOs), are presented to identify jets containing the hadronic decay of W/Z bosons and top quarks,...
The use of jet substructure techniques to identify highly boosted top/W/Z/H/b jets has become an important tool for physics searches and measurements at the LHC. We present the latest jet tagging techniques in CMS, including state-of-the-art machine learning methods.
